Can Custom Authentication Procedure Change APP_USER?

Question

I have a custom authentication procedure that authenticates the user against Active Directory. In the procedure, I look up the user's proper case name, using the non-case-sensitive user name they typed in.
I'm doing this:
HTMLDB_CUSTOM_AUTH.set_user(p_user => s_username);
OWA_COOKIE.send(NAME => 'LOGIN_USERNAME_COOKIE', VALUE => v('APP_USER'));
The cookie seems to be correct, but the area at the upper right of each page doesn't show the proper case username and the client_id column of the dba_audit trail view doesn't show it either.
What am I doing wrong?

Hi Scott.
In my authentication scheme, I have this for my Athentication Function:
return dar_authentication_pack.get_user_authenticated_func
The function is declared like this in the package specification:
FUNCTION get_user_authenticated_func(
p_username IN VARCHAR2,
p_password IN VARCHAR2,
p_preserve_case IN BOOLEAN DEFAULT True
RETURN BOOLEAN;
In my login page, the "Login" Page Process is this:
begin
wwv_flow_custom_auth_std.login(
P_UNAME => :P101_USERNAME,
P_PASSWORD => :P101_PASSWORD,
p_preserve_case => True,
P_SESSION_ID => V('APP_SESSION'),
P_FLOW_PAGE => :APP_ID||':4'
end;
I'd like to be able to change APP_USER from what the person entered to the Proper Case version of it that I have found in Active Directory. What is the best way to do this?
